LEAPprimary significantly reduces overall energy consumption, costs and physical space requirements by combining separation, thickening and dewatering of primary wastewater solids into one compact, high-performance unit. It replaces conventional clarification and fine screening in a typical MBR plant.
LEAPprimary offers high removal of total suspended solids (50-70%) and biochemical oxygen demand (25-40%), and the removed solids can be dewatered to 20-30% dry matter, minimizing handling costs. Energy usage for biological treatment is reduced because solids and organic material are removed prior to secondary biological treatment. The dewatered residual product also enables energy recovery, as it is rich in organics and can be used in anaerobic digestion, incineration or other processes that convert the organics in wastewater to energy.
“The combination of LEAPprimary with LEAPmbr is the world’s latest innovation in MBR technology, and it demonstrates that exceptional effluent quality with low energy consumption is possible,” said Yuvbir Singh, general manager, engineered systems - water and process technologies for GE Power & Water. “LEAPprimary is the result of GE’s paying attention to customer needs and making the commitment and investments required to satisfy them.”
